I'm a little late replying to this but here's my two cents.

Jock looks great. His outfit is well coordinated and he carries himself with confidence. Just by looking at it, there even appears to be a lot of "matching" going on. From Jock's explanation, however, we know that he put no effort into trying to match...

When it comes to THCD, this is somewhat of a quandary to me and perhaps to others. Jock's accouterment exemplifies insouciance partly because his wardrobe has been put together over many years. Things go together without him having to agonize over it.

For someone new to the kilt, there are a lot of purchase and dressing decisions to be made. People then invariably post all kinds of things about how to "match." The THCD answer is not to concern oneself with matching but I think that is a dangerous answer for some folks, especially those living in places without a deep kilt "kulture." I think it would be better for a newbie to match than to end up erring on the side of brigadoonery...

In reviewing Jock's attire then, I am trying to observe how things tone together and how his outfit is coordinated. I see that he is only wearing colours that are found in his tartan: blue, green, red, yellow, and black. There are varying shades of these colours (i.e. bonnet, jacket, and tartan contain 3 different greens) but they compliment not clash.

He is also mixing things up so that flashes, hose, shirt, tie, and jacket go with the tartan as opposed to each other; none of them are the same, matching colour. This avoids the so called "tartan sandwich" of hose and shirt matching. There is contrast without conflict and it all comes together around the tartan. Not to make a rule out of this one example, but that could be be a rather good guideline for THCD...

If I really exert myself to find anything to nitpick, I could only say that a man of Jock's stature could pull off a bigger knot on his tie
